Tellabs ® 1100 Multiservice Access Platform Series — 

Ethernet Switching Unit (ESU) 

Overview 

The Ethernet Switching Unit (ESU) provides multi-Gigabit Ethernet 

switching capability to the Tellabs ® 1100 Multiservice Access Platform 

(MSAP) Series. Acting as the central switch fabric, the ESU module 

contains a non-blocking, wire-speed IP/Ethernet switching engine that 

aggregates, processes and forwards all datagrams between the network 

interface(s) and end users. 

ESU11 



With two ESU modules per MSAP in a primary and protect configuration, 

Ethernet Link Aggregation is used to load-balance both modules 

and effectively double the processing capacity of the system. Standard 

Small Form-factor Pluggable (SFP) and 10 Gigabit Small Form-factor 

Pluggable (XFP) modules are utilized for flexible network interfaces, 

supporting a wide range of physical media, wavelengths and optical 

budgets. 

Flexible VLaN Methodologies 

Designed for flexible and powerful network integration into business, 

enterprise and carrier environments, the ESU module offers multiple 

Virtual Area Network (VLAN) methodologies to support today’s 

advanced IP services including business, residential and triple play 

deployments. The combination of 1:1 VLAN, 1:N VLAN, and Q-in-Q 

VLAN provisioning models is available for high-speed data, Voiceover-IP 

(VoIP), IP Video and Video on Demand (VoD) delivery for 

business, enterprise and residential service. Transparent LAN 

Service (TLS) is also available for business applications. 

security architecture 

The proper security architecture is imperative for IP-based access 

networks. The ESU module forms the core of a strong system 

security architecture necessary for operating in a Layer 2 switched 

environment. When operating in either Ethernet Bridging or Forced 

Forwarding modes, the following powerful security measures are 

available to help mitigate the occurrence of malicious attacks on 

the network. 

• Broadcast Rate Limiting — Rate limiting at the end user port; 

allows any datagram type to be rate limited in increments of 

64Kbps. Typically used for broadcast ingress control. 

• access Control Lists — Ingress datagram filtering supports 

Layer 2 (Ethernet), Layer 3 (IP), Layer 4 (TCP/UDP) fields 

• User authentication — Support for Dynamic Host Configuration 

Protocol (DHCP) or Point-to-Point Protocol over Ethernet (PPPoE), 

provisionable per subscriber port, including DHCP Option 82 and 

PPPoE Intermediate Agent functions 

• Port-based Network access Control — Strong user authentication 

compliant with the 802.1x standard using distributed encryption 

keys. A RADIUS interface is provided to the authentication system. 

Quality of service 

The ESU module utilizes 802.1p for prioritization and control of 

bandwidth allocation. Each service flow is designated with one of eight 

priority levels with policing, queuing and scheduling algorithms controlling 

bandwidth allocation and delivery mechanisms within the system. 

Per-subscriber rate limiting is offered to control committed and excess 

bandwidth delivery of differentiated services, including high-speed data, 

multicast IP video, unicast IP video and TLS. DSCP to 802.1p mapping 

is provided at all end user ports.

IP Video Processing 

Utilizing Internet Group Management Protocol (IGMP) transparent 

snooping with proxy reporting for control of multicast IP video service, 

the ESU module supports both IGMPv2 and IGMPv3. Thus, service 

providers gain the flexibility to deploy current generation set-top boxes 

or next-generation personal entertainment home gateways. This 

capability to support simultaneous deployment of IGMPv2 and 

IGMPv3 set-top boxes within the access network creates a unified 

IGMPv3 edge/core network presence.
